The Pearl G-Series line of controls is designed to meet the environmental control requirements of most standard greenhouse applications. The different models are designed to match the complexity and requirements of the grower and are compatible with standard greenhouse equipment utilized by growers.

The unique design allows for greater expandability and flexibility for the grower. You can add input and output modules to expand to your specific requirements. With the integrated panel option, your controls can be mounted with the required contactors for easy installation and the assurance that your controls are connected properly.

The Pearl G-Series can be programmed at the controller with basic programming functionality or connect to the Link4 Cloud to enhance the operation of your controller. The Cloud offers the grower the ability to remotely control, monitor and receive alarm notification allowing you to stay connected to your operation while you are away.

User friendly screens allow you to easily program, change, and monitor all of your controllers that are connected to the Cloud from a single source. You will be able to assign users with specific access levels, add grower, or maintenance notes, or store photos, and assign tasks through the Cloud. In addition, you can identify important growing trends and ensure future crop success via insights gained using reports and graphs derived from data stored on the Cloud.

All Pearl model controllers are compatible with the Link4 Cloud allowing for remote accessibility and control, as well as added advanced features.

The Cloud allows you to view and operate your controller from remote locations at any time. Set up user security and accessibility per user and zone. View your current status and create custom reports, or download the data for further analysis. View any alarm status for your zones and receive notifications regardless of your location. With the Grow Journal and Task Manager, you can enter grower notes, photos or videos, and assign tasks as required.

Cloud pricing is monthly or a discounted annual fee based on the model and number of controllers.

LinkConn Software

Link4’s LinkConn software makes controlling your greenhouse easier than ever. Unlike large cumbersome PC interfaces, or very basic limited ones, LinkConn gives you total control over your growing operations in a format that makes sense to growers. The typical learning curve for LinkConn software can be measured in minutes. The speed at which you can review greenhouse status and make detailed changes can be measured in seconds. The layout is so friendly that even when you aren’t making changes often, it only takes a few minutes to find what you’re looking for. Whether you have one or one hundred greenhouses, LinkConn manages them all the same in a simple and easy manner from one location.

Smart Irrigation

The iGrow 1800 uses a VPD (Vapor Pressure Deficit) feeding system or Smart Irrigation Sensors. VPD saves nutrients by preventing over-watering and makes sure the plants always have as much water as they need. This is a unique benefit as it’s designed to conserve water.

Smart Lighting (Daily Light Integral)

The iGrow 1800 offers DLI intelligence. DLI intelligence controls your greenhouse’s grow lights to give the exact amount of light needed for success. DLI intelligence conserves energy by using sunlight whenever possible.

Auxiliary Controls

The iGrow’s 1800 auxiliary controls are flexible and user defined to control conditions to fit your unique growing requirements. Auxiliary controls can be expandable to 36 outputs on a single controller.

  • NEMA4 enclosure; DISM sensor included

The iPonic 614 and 624 Commercial controllers are designed for your convenience – pre-mounted, pre-wired, and pre-tested. Pre-mounted means an easier and cheaper installation process. There is no need for separate boxes with connecting conduits. Pre-wired means it works as soon as you take it out of the box.

The iPonic Commercial enables growers to control a single or dual zone – with cloud-access from any Internet-connected computer or smartphone.

Unlike most controllers on the market, the iPonic Commercial controller allows total flexibility using software-based intelligence. This means that you can program all functions together and eliminate multiple controllers for multiple functions. The iPonic does it all: Fuzzy Logic CO2, light timer, irrigation, temperature, humidity, recycle timers, vent fans, high temperature shut-off, central air conditioning, and heating. You can even add your own custom devices. This also means that you can change devices on the fly and add or delete devices to match the equipment in your grow house in minutes.

Controller includes a single (or dual) Digital Integrated Sensor Module (DISM). The sensor measures temperature, humidity, CO2, and lighting.

Remote Cloud Access

Growers can monitor and change every aspect of the iPonic Commercial from the palm of their hand, using state-of the-art controls that relay secured, encrypted grow house data to the cloud where it is accessible on any Internet-connected device. The secured, encrypted server allows you to monitor and change settings remotely. With a wealth of data at their fingertips, growers are able to grow bigger, more vibrant crops under repeatable processes. No data collected by the iPonic Cloud is shared to a third party. Additionally, any location data we collect is anonymous and cannot be associated with a user account.

Digital Integrated Sensor Modules (DISM)

The iPonic Commercial includes a single Digital Integrated Sensor Module (DISM). The sensor measures temperature, humidity, CO2 and lighting and is connected by a standard 16-foot cable. It is recommended that the sensor is hung in a central location within the grow facility. Ideally, you will want to hang the module near the crop level, close to the center of the controlled environment to get accurate readings. You may want to keep the module away from irrigation emitters, unit heaters and any other type of equipment that may affect the accuracy of the sensor.

Fully Automated Control of the Entire Growth Cycle

The iPonic Commercial allows you to control each device individually with manual settings or fully automatically with all devices working together. Entire growth cycle settings can be programmed and saved on the removable USB thumb drive. This allows you to run custom growth cycles with programmed settings for every device on a week by week basis. These programs can be saved and even shared with other growers.
